Hi all, I plan to change data of cell library ,
but something I don't understand.
This is D-Flip Flop(DFF) data of cell library :
cell(QDFFLTX1) {
.
.
.
pin(D) {
nextstate_type : data;
direction : input ;
capacitance : 0.001165;
internal_power() {
when : "!CK";
power(POWER_7x1) {
index_1 ("0.009652,0.016106,0.025992,0.046675,0.088958,0.216628,0.447814");
values("0.003651,0.003635,0.003626,0.003611,0.003614,0.003725,0.004117");
}
}
.
.
.
pin(CK) {
direction : input ;
capacitance : 0.001915;
max_transition : 0.217000;
clock : true;
internal_power() {
power(POWER_7x1) {
index_1("0.009651,0.016105,0.025992,0.046675,0.088957,0.216628,0.447814");
values("0.004066,0.004029,0.004007,0.004000,0.004050,0.004346,0.005062");
}
}
What do the value mean?
And how can I measure by hspice?
but something I don't understand.
